Earlier iOS 6 releases attempted to fix a bug when connecting to Exchange servers, and while things are a lot better than they used to be, apparently the situation isn’t quite resolved 100%, and some abnormal behavior has been reported under iOS 6.1.3. Other previous issues we thought were fixed pop back up again in 6.1.3, like problems connecting to WiFi networks.

Battery drain is a nebulous issue that always seems to creep up with a new update, and this time is no exception; users are once again complaining about some pretty significant changes in how long their iOS gear holds a charge after upgrading to iOS 6.1.3. Some users have also had the update totally mute their phones, mysteriously rendering them unable to produce a sound.

Have you noticed any problems like these, or maybe something else altogether, since installing the update?
